SPECIFICATION forming part of Letters Patent No. 700,734, dated May 2'7, 1902-.

Application filed September 24,1901. Serial No. 76,399. (No model.)

My invention relates to vaults for the re,

ception of burial-caskets, and has for its object to provide a permanent and durable Vault which will be impervious to moisture and will resist the attacks of burrowing animals, while permitting of a natural ventilation of the interior of the vault and the'escape therefrom of the gases caused by the decomposition of the contained body. I

To these ends my invention consists in the features of construction and arrangement hereinafter described, and'pointedout in the claims.

In the drawings, Figure l is a longitudinal vertical section. Fig. 2 is a longitudinal hori zontal section on line 2 2 of Fig. 1. Fig.3 is

a transverse vertical section taken on line 3 3 of Fig. 1, and Fig. 4 is an enlarged detail view of a portion of Fig. 1.

A represents the casing-walls of the vault, preferably formed of concrete and of dimensions suitable to receive one or more cofiins.

B is a roofing-plate, preferably of metal, having its edges embedded in the side walls of the vault and constituting a support and form for the concrete top C.

One of the end walls of the vault is preferably thickened to form an enlargement, as shown at D, extending the entire height of the vault and projecting upward abovethe-top thereof, as shown at E. The vertical extension E is preferably of greater thickness thanisarrangeda suitable check-valve H, preferably of'theball construction. shown; arranged to open to permit egress of the gases from the vault,but to close against theingress of water or other foreign substance from the exterior. The opening G is preferably protectedbya covering .of grave] or other porous'mate'rial,

whichwill prevent thefaperture frombecoming'clogged with earth or clay and which will assist in disseminating the escaping gases.

The conduit herein referred to is preferably molded during the construction of the vault, and if found more convenientthe whole vault may bebuilt-t'n situ. 7

Throughout the foregoing specification and in the following claims I have for convenience employed the term concrete we describe the material of which the Vault is composed; but I wish it to be understood tlfat I'have used sai'dterm as generic to all compositions, such as cement and the like, adapted to'be molded wh ilein a plastic condition. 5 'Having-thus described my invention, what I claim, and desire to secure by L'etters Pat out, is. f H

1. A concrete burial-vault having an extended portion integral with a wall, a conduit 'formed within said extended wall establishing communication between the interior and exterior of the vault, and a check-valve in said conduit for preventing the ingress of foreign matter into said vault through said conduit. 2. A concrete burial-vault having an integral upward extension above one wall terminating at the level of the ground, a conduit located within said extension and the wall, extending upward from the interior of said vaultinto the extension and thence downward through the wall, and terminating at the exterior of the'wall near the bottom thereof,
